You're not in competition with anyone but yourself. Outdo your past, not other people.

It is never too late to become what you might have been

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Try and do one thing each day that you would really rather not do.

We learn more from failure than we do from success.

The road to success is like a staircase. If you want to succeed, double your failure rate

Just stick with it, what seems hard now will one day be your warm up.

It doesn’t matter where you start, it matters how you end

We learn more from failure than we do from success.

Pure mathematics is in its way, the poetry of logical ideas.

Everything you want is on the other side of fear

Failure to prepare = preparing to fail

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Procrastination makes easy things hard and hard things harder.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
